ning rails are transmitted up .thru the wheels, 1

axles, bearings, equalizers and other parts of the truck, to the carunderframe and body.

This invention seeks to prevent this transmission of such. shocks thruthe-side bars.

The invention comprises the novel structure and combination of partshereinafter described and more particularly pointed out and defined inthe appended clalms.

In the accompanying drawings which illus- 'trate a preferred form ofthis invention, and

in which similar reference numerals refer to similar features in thedifierent views:

Figure 1 is a fragmentary side elevational view of'a railway carshowingthe side bearing s supported according to this invention.

igure 2 is an enlarged sectional view so through one of'thersidebearings.

Figure 3 is a top plan view of a cushioning element that may be used tocushionthe side bearings.

Figure 4 is an enlarged sectional view taken upon the line IV-'IV ofFigure 2. 1

Figure 5 is .a plan view of the modified cushioning means that may beused.

Figure 6 is a fragmentary elevational view, illustrating a cushionelement between the body bolster and truck bolster;

In connection with this invention, there is shown a portion of thesideof a railway car and its truck. One of the side bars of the car is.represented by the reference numeral 1 with its ends secured to thetransverse members 2. According to this invention, a cushion retainer 3is placed upon the outer ends of each transverse member 2 and issuitably alpertured for receiving the bolts 4 that secure t e side bars1 tothe beam 2. This retainer is 1929.- 83ml 30,380,835. provided withsuitable upstanding marginal its expansion in order that it will-alwayspart a goodyield and retain its full resiliency.

The cushion itself may assume various flanges for confining the cushionand limiting forms, and in Figures '3 and 5 different forms have beenillustrated. In Figure 3, the cush-v ion consists of a center plate 5with anoblong rubber ring or element 6 attached upon each side, wherebythe securing bolts 4 may pass through the oblong rubber element.

- In Figure 5, there is illustrated a sli htly modified form in which aplurality o circular rubber elements 7 may be secured upon one or bothsides of a plate 8 with the securing bolts 4 passing through the twooutermost rings.

In Figure 6, there is shown a truck bolster 2 and a body bolster 10. Aresilient cushion 11 confined in a retainer is positioned adjacent oneof said bolsters, in the present instance it is shown associated withthe body bolster 11. The retainer 12 carries'a contact block 13 thatcontacts the contact block 14 on the truck bolster- The retainer 12 is1'0- vided with attaching flanges12", spaced rom the bolster 10andslidably supported upon the bolts 15.

. It will be appreciated that these cushionin g elements will tend toeliminate shocks and jars that have heretofore arisen dueto the metal tometal contact of the side bars with the cross members 2, and it willfurther beappreciated that the cushioning elements are con fined againstexpansion beyond a certain l1m1t, thereb lnsuring a good yield andcushioning e ect at all times. Further, the CllShlOIllIlg elements areheld and protected against wear and tear, and due to the fact that theyare securely anchored, there can be no shifting movement thereof.

I am aware that numerous details of construction may be varied througha' wide range 1 a tending side bar, cross members attached to the endsthereof, resilient means'between said cross members and the ends of saidside bar,

and means for confining and limiting the action of said resilient means.

2. In a railway car embodying aside bar and transverse members securedto the ends, of said side bar,a cushion retainer upon each cross memberand a resilient rubber cushion in am eachretainer for limited lateralexpansion.

3. In a railway car having a side bar and transverse members attached tothe ends of said side bar, a cushion retainer upon each side barv and acushion element in each reu tainer upon each side bar and a cushionelement in each retainer having an aperture for receiving the securingmeans of said side bar.

4. In' a railwav car, having a side bar, cross I members secured to saidside bar, expansible rubber elements between said cross members and sidebar and retaining means for housinp' said rubber elements and limitingthe expansible movement thereof. a

In testimony whereof I have'here'unto sub- 15 scribed my name atChicago, Cook County,
